Trajectory capture is OpenClaw's per-session flight recorder. It records a
structured timeline for each agent run, then /export-trajectory packages the
current session into a redacted support bundle.
Use it when you need to answer questions like:
If you are filing a broad support report for a live Gateway issue, start with
/diagnostics. Diagnostics collects the
sanitized Gateway bundle and, for OpenAI Codex harness sessions, can also send
Codex feedback to OpenAI servers after approval. Use /export-trajectory when
you specifically need the detailed per-session prompt, tool, and transcript
timeline.
Send this in the active session:
/export-trajectory
Alias:
/trajectory
OpenClaw writes the bundle under the workspace:
.openclaw/trajectory-exports/openclaw-trajectory-<session>-<timestamp>/
You can choose a relative output directory name:
/export-trajectory bug-1234
The custom path is resolved inside .openclaw/trajectory-exports/. Absolute
paths and ~ paths are rejected.
Trajectory bundles can contain prompts, model messages, tool schemas, tool results, runtime events, and local paths. The chat slash command therefore runs through exec approval every time. Approve the export once when you intend to create the bundle; do not use allow-all. In group chats, OpenClaw sends the approval prompt and export result to the owner privately instead of posting the trajectory details back to the shared room.
For local inspection or support workflows, you can also run the approved command path directly:
openclaw sessions export-trajectory --session-key "agent:main:telegram:direct:123" --workspace .
Trajectory export is an owner command. The sender must pass the normal command authorization checks and owner checks for the channel.
Trajectory capture is on by default for OpenClaw agent runs.
Runtime events include:
session.startedtrace.metadatacontext.compiledprompt.submittedmodel.fallback_step, including the source model, next model, failure reason/detail, chain position, and whether fallback advanced, succeeded, or exhausted the chainmodel.completedtrace.artifactssession.endedTranscript events are also reconstructed from the active session branch:
Events are written as JSON Lines with this schema marker:
{
"traceSchema": "openclaw-trajectory",
"schemaVersion": 1
}
An exported bundle can contain:
| File | Contents |
|---|---|
manifest.json | Bundle schema, source files, event counts, and generated file list |
events.jsonl | Ordered runtime and transcript timeline |
session-branch.json | Redacted active transcript branch and session header |
metadata.json | OpenClaw version, OS/runtime, model, config snapshot, plugins, skills, and prompt metadata |
artifacts.json | Final status, errors, usage, prompt cache, compaction count, assistant text, and tool metadata |
prompts.json | Submitted prompts and selected prompt-building details |
system-prompt.txt | Latest compiled system prompt, when captured |
tools.json | Tool definitions sent to the model, when captured |
manifest.json lists the files present in that bundle. Some files are omitted
when the session did not capture the corresponding runtime data.
By default, runtime trajectory events are written beside the session file:
<session>.trajectory.jsonl
OpenClaw also writes a best-effort pointer file beside the session:
<session>.trajectory-path.json
Set OPENCLAW_TRAJECTORY_DIR to store runtime trajectory sidecars in a
dedicated directory:
export OPENCLAW_TRAJECTORY_DIR=/var/lib/openclaw/trajectories
When this variable is set, OpenClaw writes one JSONL file per session id in that directory.
Session maintenance removes trajectory sidecars when their owning session entry is pruned, capped, or evicted by the sessions disk budget. Runtime files outside the sessions directory are removed only when the pointer target still proves it belongs to that session.
Set OPENCLAW_TRAJECTORY=0 before starting OpenClaw:
export OPENCLAW_TRAJECTORY=0
This disables runtime trajectory capture. /export-trajectory can still export
the transcript branch, but runtime-only files such as compiled context,
provider artifacts, and prompt metadata may be missing.
Trajectory bundles are designed for support and debugging, not public posting. OpenClaw redacts sensitive values before writing export files:
$WORKSPACE_DIRThe exporter also bounds input size:
Review bundles before sharing them outside your team. Redaction is best-effort and cannot know every application-specific secret.
If the export has no runtime events:
OPENCLAW_TRAJECTORY=0OPENCLAW_TRAJECTORY_DIR points to a writable directorymanifest.json for runtimeEventCountIf the command rejects the output path:
bug-1234/tmp/... or ~/....openclaw/trajectory-exports/If the export fails with a size error, the session or sidecar exceeded the export safety limits. Start a new session or export a smaller reproduction.
